Rocket Pocket Bikes Make sure you properly mix your 2 cycle (2 stroke) oil with your gas. (Use low or middle grade gas, anything higher will over heat your bike and void your warranty) Rocket Pocket Bikes are mixed at a 32:1 ratio (said 32 to 1) or a 35:1 ratio. These are good mixture ratios to run your rocket pocketbike. If you have read your pocketbike manual, Follow these instructions listed Here, your manual is wrong.

#5 How do I prep my Pocket Bike or Gas Racing Scooter or Gas Skateboard?

Once you have mixed the gas/oil and fill your rocket pocket bike or gas racing scooter up. Next you will want to very slowly with a short pull, Extend the pull start chord out so you feel the motor turn over. When pulling the pull start chord out always use short strokes, this drastically extends the life of the bike. Do not forget to follow instruction #1 above.

The slow pulling is siphoning the gas/oil into the Brand New (Completely Dry) motor chamber. This process will lube your rocket pocket bike or gas racing scooter piston and cylinder wall (The Motor) Repeat this process at least 20 times to make sure you have lubed your rocket pocket bike or gas racing scooter motor.

2. Make sure your fuel on/off lever is turned to the on position to let the flow of gas through. The on/off lever is the white thumb tab on your carburetor. If gas is leaking out of your pocket bike as soon as you do this, you will want to go to a scooter or pocket bike shop and get a fuel filter to put on your gas line of your pocket bike.

3. Put your choke lever to the on position. This may not necessarily be the same as how the on/off position is labeled on the pocket bike. (When the choke is in the on position the lever will be covering (blocking) the intake hole, hence choking the pocket bike out) When the choke lever is in the off position the intake hole will be open letting in as much air as possible.

4. Now find the screw on the side of the Carburetor that has a little spring on the shaft of it. This is your air/fuel mixture screw. If you have a Full Fairing (Fairings are the side plastics on the pocket bike) Pocket Bike you will have to take the Fairing off to see the carburetor.

As a good starting point you will want to gently turn this screw all the way to the right till it stops. Then turn a full turn to the Left. Put your rocket pocket bike on the bike stand with the rear tire off of the ground. From here you will start the pocket bike with the choke lever in the on position. (blocking the intake) Then turn the throttle lever a little so the pocket bike starts easier. Now you can pull the pull start with a short quick stroke. The bike should start with in 10 strokes. Make sure you follow instruction #1 above.

If your Rocket Pocket bike does not start, use Carburetor Cleaner. Take the spark plug wire off of your spark plug. Then remove your spark plug. Spray some Carburetor Cleaner into the hole. Screw your plug back in till it is snug. Put the spark plug wire back on your Rocket Pocket bike carb and pull the pull start with a short quick stroke. Turn the throttle handle a little or have someone help you. Your bike will fire up with in 10 strokes.

Leave the rocket pocket bike warm up for a few minutes once it starts. Twisting the throttle handle (giving it gas) to make sure it does not stall out. You will want to throttle the pocket bike and listen to the motor to see what kind of pitch and power the motor is giving off. Then tune the air/fuel mixture screw (screw with the little spring on the shaft of it) a 1/16th (remember this means ever so slightly) of a turn to the left. Then follow it by turning the throttle and listening to your rocket pocketbike.

The immediate goal is to be able to turn the choke off and still have the rocket pocket bike idle. The next goal is to be able to have the carburetor finely tuned so your rocket pocket bike will go top speed (Super Fast).

You will want to throttle the pocket bike and listen to the motor to see what kind of pitch and power the motor is giving off. Then tune the air/fuel mixture screw a 1/16th (remember this means ever so slightly) of a turn to the left. Then follow it by turning the throttle and listening to your pocket bike.

Carefully repeating the steps by revving the motor, listening and then ever so slightly tuning the air/fuel mixture screw. This process will change the pitch and power the motor gives off.
Once the motor gives off some power you can even go for a quick spin on your new rocket pocket bike and come back and tune it again.

You will be repeating these tuning steps all the while listening to your rocket pocket bikes motor. The rocket pocket bike motor will sound smoother and more powerful after some tuning. If you go too far, at one point you will hear the motor sound powerful and smooth then just drop off. At this point you will want to step backwards and tune to the right 1/16th of a turn.

Tuning the Carburetor for Gas Scooters, Gas Skateboard or Large Full Fairing Pocket Bike: Gas Racing Scooters Gas Skateboards, and Large Full Fairing Pocket bikes do not come pre-tuned, so follow these easy instructions and you will be on your way in no time.

This controls the amount of air and fuel your motor is receiving.

You are going to want to GENTLY but FIRMLY turn that screw all the way to the right. Then back it off (turn it to the left) a full turn. This will be your carburetors starting point.

The screw with the spring on the shaft of it is your idle adjustment screw. Turn this screw all the way to the right. Then back it off a full turn to the Left.

Prime the motor (push the squishy clear bubble 2 times) with the primer bulb. You are going to then prop the back wheel of the scooter off of the ground.

Start the gas racing scooter or full fairing pocket bike (OUTSIDE, Not in a House or Garage) by putting the choke on position (blocking the intake) Then pull the pull cord with a short quick stroke (Make sure you follow instruction #1 ). The gas racing scooter should start with in 10 pulls.

Keep following the above steps, all the while throttling the motor and listening to it. Eventually you will hear the motor purr that is where it should be tuned.

This is caused by a bent sprocket the chain not being aligned properly, or the motor not being aligned.

The chain can be adjusted in 2 ways. First you want to make sure the rear tire is straight. Just eye ball it and you should be able to tell if it's straight or not. If it's not straight loosen the nuts that hold the wheel in place. Adjust the chain tightening screws in the back until wheel is straight. If your chain still looks crooked then you need to adjust the motor. To adjust the motor simply lay the scooter on its side so you can get to the bottom of the motor. You will see 3 screws. Loosen all 3 screws a little. Put some lock tight on the screws before tightening the screws back. Then straighten the motor until the chain looks straight and your chain will never fall off again.
